Even though she's dealing with a scar, Emily just carries on with life. It's not a big deal. While we were shooting the scene, I tried it different ways. I tried it where I was hiding my face, and Chris [Weitz] was like, "Let's try it where she doesn't care," and that's who she is. She doesn't care what anybody else thinks.

After the make-up process, I was like, "I never want to do a sci-fi movie where I'm in make-up for seven months." It's interesting. It was my first time ever getting prosthetics. They put this goopy stuff all over your head and they tell you it's like a facial, but it's actually very claustrophobic. All they have are these places where your nostrils are and I kept thinking that they were closing up, but they were like, "No, we're looking at it." So, they made a mold of my face.

he first make-up crew had three test runs, so by the time we were shooting, they got it down to three hours. They switched make-up crews for Eclipse and they never had any test runs, and they had to figure out what the other team had done, so the first day, I was in the chair for eight hours. But, they adjusted the scar from New Moon to Eclipse. The first time, there was more pullage on my face, so I had a hard time eating. It didn't hurt, but it was uncomfortable.

It was a realization for me when Oprah was talking about New Moon. I was like, "Oh, my god, she's watched a movie that I've been in!" People were like, "It just kicked in for you?," but it's just work for me. The idea that somebody that I've admired for so long had seen something that I'd done was when I understood the magnitude of it.

I was in the car driving back, after having done a scene where I kill somebody, and I just said to the driver, "I can't talk right now. I'm too emotional." The whole car ride back, I was just crying.

Yes, there was a massive difference between their styles. David is a very technical director and Chris is an actor's director, in the sense of emotion. With David, he's done horror films, so Eclipse is much darker, whereas I found New Moon really light and poetic. I didn't have as much interaction with David because the casting process was already done.
